DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z August 31, 2007

SE PA:
A fire in far SE PA near the MD/DE state lines is producing a very thin
plume of thin smoke that extends due south to the MD state line though
the plume has turned clockwise in direction throughout the day.

SE US/Atlantic Ocean:
A very thin pocket of remnant smoke from Idaho/Montana fires along with
some haze/pollutants can be seen moving SE off the SC coastline into the
Atlantic Ocean then curving back S and SW to western FL centered around
West Palm Beach.  Most of this smoke is very difficult to see since it
is mixing out quickly even with low sun angle.

Great Plains (KS to SD):
Smoke from yesterday's ID/MT burning has drifted out into the Great Plains
and has slowed down and started to drop southward.  The largest pocket of
moderately dense smoke covers much of the NE and central SD and is very
slowly making the turn from due east to southward movement. A second area
or arc of moderate smoke is at the leading edge of the upper level flow
across S KS, arching back to around KC, an associated more dense pocket
can be seen moving across the NE/KS line near Gage and Marshall counties.

Wyoming:
A large fire on the western side of the Northern Bighorn Mtns in N WY
is producing dense smoke that covers all of Sheridan county as it moves
ENE. The leading edge of thinner smoke has reached the MT/SD line just
north of WY. The plume is over 100km wide at its widest point over N
WY/SE MT and has been mixing with the larger area of moderate/dense
smoke that is described below in the ID/MT section.

Idaho/Montana (SW ND too):
Similar to most evenings this summer, the large fire complexes of the
central ID mtns and NW mtns of MT continue to pump out very dense smoke
that is moving ENE covering nearly all of MT (except extreme NW MT where
there are no fires) and all of central ID from S Clearwater county in
the north to central Custer county in the south and from western Valley
county to MT. A small extension of moderately dense smoke extends across
the SW ΒΌ of ND as well.
A large blow up of convectively dense smoke from a fire just SE of Mesa
in Adams county extends ENE (about 60km) to the large fires in western
Valley county in a 25km wide plume.

Oregon:
An amazing abundance of agricultural fires which started about the same
time around 21Z in the the Willamette valley of from the Lane county line
to northern portions of Marion county is currently producing multiple
puffs/plumes of smoke that have combined into a large area of thin to
moderately dense smoke that is moving NE and covers all of the western
Cascade slope counties of Multnomah, Clackamas, Marion, Linn with portions
of Hood River (OR), Clark (WA) and Skamania (WA) counties as well.
Washington:
The Domke Lake Complex is producing convectively dense smoke that extends
NE in a 36km wide plume that reaches the CN boarder near the intersection
of Okanogan and Ferry counties.  This smoke mixes at this point with the
western portion of a fan of moderate to dense smoke from a new fire on
the western portions of the Colville Reservation south of Okanogan near
Omak Lake.  The fan is about 35 km wide but centered from the fire to
the CN boarder near 118W.

California:
A fire near the San Mateo/Santa Cruz/Santa Clara intersection is producing
a narrow plume (10km) of moderate smoke that is moving NE to around Lodi
and Stockton.
The Wallow fire in western Trinity county is producing dense smoke that
is moving NNE and covering nearly all of the central and northern portions
of the county.

Hawai'i:
New lava flow from July 21st Fissure of Kilauea volcanic field is
burning a small patch of trees that is producing thin smoke which is
mixing with Fume and Vog and extends SW and curls around the southern
portion of Hawai'i (island).

Alaska:
Large fire near 69N150.5W is producing thin smoke that is moving due
south into the Brooks Range and up the Nanushuk River Valley. The plume
is about 20-40km wide.
A fire near 66.4N143.9W is producing thin to moderate smoke that is
moving S then turning SSE. The plume extends about 60km in a line on
average about 20km wide.

Gallina:

 


Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
